TREATING METHOD OF CONSTRUCTION REMOVAL MUD AND EARTH RETAINING WALL FILLED WITH CONSTRUCTION REMOVAL EARTH

摘要

PROBLEM TO BE SOLVED: To treat removal mud generated at a construction site by using steel pipes used as a core material of an earth retaining wall. SOLUTION: At execution work of the earth retaining wall by soil cement and the steel pipe, when forming an excavating hole 4 filled with the soil cement 3, the soil cement (the removal mud) discharged by overflowing on the ground is reduced in volume by performing dewatering treatment, and a sludge cake 5 of this quantitatively reduced removal mud is inputted in a steel pipe pile 1 before hardening the soil cement 3 in the inserted steel pipe pile 1 to perform backfilling treatment.
